' PLATE-CLEANING MACHINE.

Beit known that I, HERMAN Fionnnrini, a citizen'of `the United States,residing at Baltimore, (St. Helena) in the State of.

Maryland, have invented new and useful "improvements in kPlate-CleaningMachines, of which the following is a specification.

This invention relates' to means for cleaning metal plates'as they leavethe furnace and the principal object of the invention is to providemeans for cleaning both faces of the plate at the same time as the plateis drawn 'from the furnace door.

Another obj ect of the invention is to provide means for spraying theplate with water so as to cool the same and te 'facilitate the cleaningaction of the brushes.

Still another object ot the invention is to provide means whereby thesupply of water is automatically cut oil when the parts are moved intoinoperative position.V

A further object of the invention is to provide means for moving thebrushes toward and away from each other and also means for moving thewhole apparatus away from the furnace door when desired.

The invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described; illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing my invention in detail, rei'- erence will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure lis a view showing the device arranged in front of a furnace door;

Fig.i2 is an end view;

Fig. 3 is a longitudinal sectional view;

Fig. l is a section on line i-#i of Fig. 1;

Fig. 5 is a sectional detailed view through one of the brushes; Y

Fig. 6 is a plan view of the corrugated plate; Y

Fig. 7 is a view showing the device swung away from the furnace.

In these views'l indicates the door opening ot the furnace through whichthe plates are placed in and removed from the fur; nace. To one sideof'said opening I range an upright post 2 which is rotatably supportedin the supports 3 and the socket specification of Letters Parent.Patented Feb', 24, 1920,

Application filed April 5.A 1919. Serial No. 287,720.

1. This post supports at itslugper end a frame 5 and this frame isadjustable in a vertical manner yon said post 'by means ot the holes 6and the bolt 7. The `frame 5 pivotally supports the brushcarrying`frames 8 and 8. The frame 8 consists ot the two side pieces spacedapart by the eccentric rollers 9 through which the bolts l() pass whichconnect the two side pieces together. The endsot the side pieces arepivoted to the frame 5 by means ofthe bolt 11 which passes through thespacing member 12. The rollers 9 support the brush 13 and said brush isclamped between the side pieces of the frame, as shown in Fig. 4. Whenthe bolts are turned by a 'wrench or the like the eccentric rollers willalso be turned so as to force the brush outwardly and thus conipensatefor the wear oie the bristle or wires 111. The upper brush-suportingframe 8 is made similar to the ower frame, but the ends of the sidepieces of this frame are extended beyondV the pivotal point as at 8X. Awater tank 15 is located on the upper part oiE this upper iframe. ThisJrank is provided with an enlarged part 16 which is located at thepivotal endoi' the trame and with a reduced portion 17 which extendsover theV upper brush 18. The bottom of this reduced portion is providedwith perforations 19 and the bach of the brush is also perforated as at:2O so that when the water is in this reduced portion of the tank itwill pass through the perforations in the bottom of the tank and throughthe perforations in the brush and pass on to the plate. Vhen the brushis in y inoperative position the water will collect in'theenlarged part16 and vnot pass through the perforations in the reduced portion oit thetank. The upper brush holder iframe is normally held in tilted positionby the spring 18 which connects the extended end 8x withthe upper end ofthe post. The

- water inthe enlarged part 16 also tends to tom, or plate T21, providedwith small perforations 22 and corrugated as at 23, may be placed in thebottom of the tank. The top 24 of the tank is lremovable and is rsecuredin place by the straps 25 whichcommunicate with theside pieces of thetop frame. I`h`e two frames are connected together by the strips 26 vsothat Vasfth'e fupper frame moves upwardly it will carry the lower framea slight distance With it.

I make all the parts adjustabley by providingv a 'plurality 'of holesinthe parts for receiving the connecting bolts. f

I provide a supporting postV 27 for the free end of the lower framewhich carries a cross piece 27 provided with a latch 27X and I providehooks 28 for engaging eyes 29 carried-by the furnace for holding theparts against :movement Y It will .thus be seen that as the plate` A isdrawn from the Vfurnace over the lower brush, vit will lower said brushsoas to start the `upper brush moving downwardly. The operator .thencontinues the downward movement of the upper brush until it conl tactswith the upper face of the plate. Thus the act of drawing the plate fromthe furnace will clean both faces of the plate and the water passingthrough the .perforations in the bottom of the tank and the upper brushwill act to cool the plate. As soon as the upper brush is released thespring will tilt it upwardly and thus shut off the supply through theperforations.

Insomelcases I Inay swing the device into the position shown in Fig. 7in which the vbrush frames entend at right angles to the front ofthefurnace. To support the outer end of the lower brush in vthis position Iprovide a post 30 and I also provide additional supports 31 for theframe 5 when the parts are in `this position, these supports 31 einglocated on opposite sides of the post 2.

When the parts are in this position I will place the plate on Ythe lowerbrush and lclean one sideand then turn it over to -vcle-an the other. Iprefer this method for the `small plates.

-I find it desirable `to provide meansfor making. the `device capable ofholding different sized brushes and in order to do this I make the bolts10 of great length-andwprovide short rollers 32 which are lmade similar'tothe rollers-9 and these rollers 32 are placed on the ends of the boltsoutside thef-rame. Then when it isdesired to -usefa flargerfbrush theframes are extended land the rollers 32 placed Within the `frames withtheir -ends abutting the'ends of the `rollers-9. l y

It is thought from the lforegoing'-d'escription that the-advantages andnovel features of-m/ v invention will be readily apparent.

I desire it to be understood that I may make changes in the constructionand -in the combinationand arrangement of the several parte, providedvthat l such changes 'falhwith- *each other, a tank carried by`loneofithe brushes, and means for passing theV waterY Vfrom the tanklto 'said' brushes.'Y

2. A device of the class describedV comprising a pair ofbrushfsupporting frames, Y.

brushes supported therein, means lfortiltably supporting Yone of saidbrushl franies,a

tank 'carried by said tilt-able :fr/ame, the bottom of said tank beingperforated above the brushand said tank 'having' an venlargement at oneend for receiving the water whenthe brush frame is in tilted position. ji

3. A device ofthe class Vdescribed comprising a pair of brushframes,bru'shes carriedthereby, means for tiltably supporting the upperframe, means for'normally holding the said upper frame in tiltedposition, a water tank located on said upper frame, said tank having itsbottom which is located over the brush perforated Vand having anenlarged .end forreceivingthe water when the frame is .in-tiltedposition anda main supply tank connected with the first men'T tionedtank. Y n f 4. A device of the class described comprising a `pair ofbrush .supportingframes brushes supportedtherein,.rneans for tiltablysupporting the upper frame and a rotatably supported main frame for-the.brushfframes lF. A device of the class described comprising a rotatablysupported upright, a

. v 1- frame connected with the vupper endof said upright, a brushsupporting framehaving one'end pivoted to said frame, a'secondsupframe,a tank carried by said upper frame and having a perforated bottomvlocated above the brush, a false bottom adapted tto be placed abovesaid perforated bottonnfsaid false bottom being corrugated `and providedwith small perforations and said tank having an enlarged end forreceiving-the 'water when the lframe is in tilted position.
